High-purity yellow tungsten oxide, also known as high-purity tungsten trioxide, is a kind of yellow powder with high main content (WO3), low impurity content and excellent physicochemical properties compared with conventional yellow tungsten oxide. High-purity Yellow Tungsten Oxide Producing Process Yellow tungsten oxide prepared by the following process has the characteristics of fine granularity, high purity and good stability. 1. Adjust pH of sodium tungstate solution to 4~8 by using organic or inorganic acid. After hydrothermal reaction 12 hours, filtration,…

YTO, the abbreviation of yellow tungsten oxide, also called tungsten trioxide (WO3), is a yellow or bright green powder with the formula WO3-x, loose specific weight of 2.3~2.8g/cm3. The property of yellow tungsten oxide is stable at room temperature. Grades According to national standards, tungsten trioxide is usually divided into three grades, namely super grade (WO3-0), grade 1(WO3-1) and grade 2 (WO3-2). In addition, each manufacturer will produce yellow tungsten oxide with different specification because of the difference of raw…

Yellow tungsten oxide, YTO for short, has a yellow to bright green color. Its formula is WO3. It is used for the production of tungsten metal powder. Products passing 60 mesh screen. It keeps stable in the atmospheric temperature. Its apparent density is 2.3~2.8g/cm3. The crystal size is about 1.5um, it is yellow (made from tungstic acid) and is used as a catalyst. The crystal size is about 15um, showing bright green (made by calcining ammonium paratungstate), for the production…
